Nickel 200 Flanges Supplier | 201 Nickel Flanges Supplier

Precision engineering for corrosion-resistant performance, Nickel 200/201 Flanges are crafted from high-purity nickel alloys known for their excellent mechanical strength, superior corrosion resistance, and exceptional thermal conductivity. Alloy 200, the commercially pure nickel grade, performs well in alkaline, caustic, and neutral media, while Alloy 201 is designed for higher temperature stability due to its lower carbon content. Together, they deliver durable, leak-proof, and oxidation-resistant connections ideal for chemical, marine, and power industries. Their ability to maintain structural integrity under stress makes them a top choice for critical process applications.

Alloy 200 blind flanges are widely used by chemical manufacturers, power generation units, and desalination plants that need to seal pipe ends in highly corrosive or high-pressure environments. Alloy 201 blind flanges are preferred by pharmaceutical producers, marine equipment builders, and food processing units where clean, non-contaminating performance is crucial. These flanges are commonly used in heat exchangers, condensers, pressure vessels, and piping terminations, ensuring system safety during maintenance or shutdowns. Their resistance to caustic solutions, acids, and chloride-rich media allows long-lasting performance even in harsh operational settings.

Alloy 200 threaded flanges are favored by fabrication engineers, gas processing units, and small-scale industrial setups that require quick installation and compact sealing without welding. They are ideal for low-pressure pipelines, instrumentation systems, and utility connections where maintenance efficiency is key. Alloy 201 Threaded Flanges are used by refineries, petrochemical plants, and high-temperature process industries that handle hot gases, steam, or chemical streams demanding enhanced heat resistance. Whether in chemical reactors, offshore platforms, or energy systems, Nickel 200/201 Flanges combine purity, precision, and protection—ensuring dependable connections that sustain performance across the toughest industrial environments.
